sr20det ecu on sr20de

[upstate240sx]

hi,
ive done some searching and i havent found a sure fire answer , but will a rwd sr20det ecu run a sr20de that has been turboed, i kno the sr20det ecu have a coprocessor that runs the direct igniition but can the det ecu run a distributor powered motor?

Dont think so, your pretty much answered your own question. Rwd DETs run CAS while the DEs run distributors. Maybe with a rom tune its possible...

[upstate240sx]

that i can do...

Why not switch to the DET's CAS system if you could?

In any case, getting a DE ECU isn't that hard. Can use the Sentra, or G20's ECUs, IIRC.

i have a de ecu infact, i have a couple but i bought this jwt ecu not realizing it was tuned for a det, i basically bought a rwd sr20de and turboed using det parts, but using a distributor. how much boost can the stock de ecu run? i also have 370 injectors

[SoSideways]

Oh man, I have no clue.

You might want to sell the JWT ECU and send in one of your DE ECUs and tell JWT to hook you up with a turbo program for it.

Mixing and matching without knowing the specifics of the pros and cons of that setup will only lead you into trouble.

nop wont work.... i tried the same thing too. its better for you jst to go ahead a chipping the ECU. IMO.

but then agian ima be experimenting on it.

[upstate240sx]

what are you experimenting with , a way to rom rune the ecu to run a distributor?

hahaha, currently im doing the same thing right now
i have a s15 sr20de spec s motor
im got a s13 redtop harness and spices out the cam angle sensor,
the coilpacks runs in to the ignitor chip so that means i will be runing a s15 sr20de swap with ignitor chip.
